This book by the Government Printing Office (GPO) was my most important source of information in the late
1970s.  It covered each Soviet space mission in a historical way and with addition technical information
related to spacecraft radio systems, frequencies, and in particular, Soyuz PDM telemetry on 20.008Mhz
and
the VHF voice channel of 121.750Mhz.  It gave me some insight into the tracking work done by the
Kettering Group and Sven Grahn.  It answered many of the questions that I'd been seeking for years and it
was a real boost to my space tracking hobby.  NOTE- This book broke my habit of just tuning for Amplitude
Modulated (AM) voice signals on the high side of 20 megacycles.  It modified my listening strategy and
with the receiver
BFO now 'TURNED ON', I soon  discovered Soyuz PDM telemetry on 20.008Mhz.  I regret
not recognizing the
PDM telemetry earlier but my mistake, in part, was the method of listening for voice
transmissions because I was focused on hearing the Russians
talk on 20Mhz shortwave.  Prior to getting
this book, it was the
old newspaper clippings that steered my thinking toward listening on 20Mhz.  Plus,
press art from the period clearly show Russian spacecraft with long rod antennas that appear to be at
shortwave wavelength, perhaps around 20Mhz I thought ?

ABOVE- THIS RUSSIAN POSTCARD WAS CONVERTED TO A 1973 HAM RADIO QSL AND IT SHOWS
AN EARLY SOYUZ WITH LONG ANTENNAS CHARACTERISTIC OF SHORTWAVE FREQUENCIES.  
OBVIOUSLY ARTWORK IS SUGGESTIVE AT BEST AND IT CAN BE DECEIVING, SOMETIMES
DELIBERATELY SO IN ORDER TO MISLEAD THE VIEWER.  AT THE BEGINNING OF THE SPACE
RACE, THE RUSSIANS USED DECEPTIVE ART/PHOTOS TO CONCEAL THE DETAILS OF THE
POWERFUL R-7 ROCKET.  ALMOST A  DECADE AFTER LAUNCHING SPUTNIK,
THE R-7, AN
UPGRADED VOSTOK VERSION, WAS PUT ON
PUBLIC DISPLAY AT THE 1967 PARIS AIR SHOW.
ABOVE- ON APRIL 12, 1961 VOSTOK-1 CARRIED RUSSIAN COSMONAUT YURI GAGARIN
ON THE FIRST MANNED ORBITAL FLIGHT.  THIS  ARTWORK APPEARED IN THE 1967
PRESS AND SHOWS HOW THE VOSTOK BRISTLED WITH SHORTWAVE ANTENNAS.

MANNED RUSSIAN SPACECRAFT WITH SHORTWAVE ANTENNAS.
